Inventor: MATSUYAMA FUMIO
IPC: A21B3/13
Filed: 1987-06-30
Abstract: PURPOSE: To achieve an ideal square shaped baking mould by moulding a sheet of aluminum or aluminum alloy coated with a fluororesin into a square shape by press moulding. CONSTITUTION: A sheet of aluminum or aluminum alloy coated with fluororesin 2 is press-moulded into a square shape.

When B/A is smaller than 0.5, the form of bread becomes flat, and when it exceeds 1.5, press moulding becomes difficult. Elongation of the fluororesin- coated sheet need be 25% or more, and elongation of fluororesin is 350% or more for preventing cracking in the fluororesin-coated sheet by press work or whitening of resin surface at side surface parts in moulding a container.

Filed: 1983-09-06
Abstract: PURPOSE:To retrieve quickly and accurately a target track on a disk by stopping the movement of a pickup with a drive means when the coincidence is obtained between the value of comparison between an address detecting circuit and a memory means and the count value of a counter. CONSTITUTION:Address values (1-1,000) are provided from the most outer side to the most inner side of each track 1a of an optical disk 1. The address value (500) of a track to be retrieved is set to an address register 6 in the form of a binary signal. A comparator 7 subtracts the value of an address detecting circuit 4 from the value of the register 6. Then a binary signal of (300) is set to a track counter 8, and the counter 8 delivers its contents to a D/A converter 9. The converter 9 converts the binary signal of (300) into an analog signal and controls a motor driving circuit 10 to start the drive of a linear motor 3. Thus a pickup 2 is shifted at a high speed toward a track to be retrieved, i.e., to the inside of the disk 1.

Title: Input controller
Inventor: YAMADA MINAMI
IPC: G04G15/00
Filed: 1994-07-18
Abstract: PURPOSE:To enhance the operability by measuring the input duration of + or -switch, altering the time in increasing or decreasing direction every time when a predetermined time elapses, counting the number of times thereof, and altering the time to 1min digit for the count lower than N whereas altering the time to 10min digit for the count higher than (N+1) thereby realizing a quick response to both small and large alteration. CONSTITUTION:A time set switch 1 alters the set time in the increasing direction by means of a + switch 2 or in the decreasing direction by means of a - switch 3. A switch input processing section 4 processes the switch input and presents the results at a display section 10. A time count deciding section 5 measures the input duration of the + or - switch 2 or 3 based on a designation from the processing section 4 which designates to alter the time in the increasing or decreasing direction every time when a predetermined time elapses. The number of times thereof is then counted and the time is altered to 1min digit if the number of times is lower than N otherwise the time is altered to 10min digit. Over-lead time setting is eliminated because the 1 digit can be updated by a predetermined number of times and a considerable alteration can be dealt with because 10 digit can be updated when the predetermined number of times is exceeded.
